MapLayerTileTreeReference Class

A TileTreeReference to be used specifically for MapTileTrees. The reference refers to its MapTileTree by way of the tree's TileTreeOwner. Multiple MapLayerTileTreeReferences can refer to the same TileTree if the map layer settings are equivalent, meaning they have identical format IDs, URLs, credentials, etc.

Methods

Name Description
canSupplyToolTip(hit: HitDetail): boolean Return whether this TileTreeReference can supply a tooltip describing the entity represented by the specified hit.  
getToolTip(hit: HitDetail): Promise<undefined | string | HTMLElement> Return a tooltip describing the hit, or undefined if no tooltip can be supplied.  

Inherited methods

Name Inherited from Description
_collectTileGeometry(collector: TileGeometryCollector): void Protected TileTreeReference A function that can be assigned to TileTreeReference.collectTileGeometry to enable geometry collection for references to tile trees that support geometry collection.
_createGeometryTreeReference(): undefined | GeometryTileTreeReference Protected TileTreeReference Create a tile tree reference equivalent to this one that also supplies an implementation of GeometryTileTreeReference.collectTileGeometry.
accumulateTransformedRange(range: Range3d, matrix: Matrix4d, frustumPlanes?: FrustumPlanes): void TileTreeReference  
addLogoCards(_cards: HTMLTableElement, _vp: ScreenViewport): void TileTreeReference Add attribution logo cards for the tile tree source logo cards to the viewport's logo div.
addToScene(context: SceneContext): void TileTreeReference Adds this reference's graphics to the scene.
collectStatistics(stats: RenderMemory.Statistics): void TileTreeReference Record graphics memory consumed by this tile tree reference.
computeTransform(tree: TileTree): Transform Protected TileTreeReference Compute a transform from this tile tree reference's coordinate space to the IModelConnection's coordinate space.
computeWorldContentRange(): Range3d TileTreeReference Compute the range of this tile tree's contents in world coordinates.
createDrawArgs(context: SceneContext): undefined | TileDrawArgs TileTreeReference Create context for drawing the tile tree, if it is ready for drawing.
createGeometryTreeReference(): undefined | GeometryTileTreeReference TileTreeReference Obtain a tile tree reference equivalent to this one that also supplies an implementation of GeometryTileTreeReference.collectTileGeometry, or
decorate(_context: DecorateContext): void TileTreeReference Optionally add any decorations specific to this reference.
discloseTileTrees(trees: DisclosedTileTreeSet): void TileTreeReference Disclose all TileTrees use by this reference.
draw(args: TileDrawArgs): void TileTreeReference Adds this reference's graphics to the scene.
getAppearanceProvider(_tree: TileTree): undefined | FeatureAppearanceProvider Protected TileTreeReference Return a provider that can supplement the view's symbology overrides.
getClipVolume(tree: TileTree): undefined | RenderClipVolume Protected TileTreeReference Return the clip volume applied to this reference's tile tree, if any.
getHiddenLineSettings(_tree: TileTree): undefined | Settings Protected TileTreeReference Return hidden line settings to replace those defined for the view.
getLocation(): undefined | Transform TileTreeReference Supply transform from this tile tree reference's location to iModel coordinate space.
getSymbologyOverrides(_tree: TileTree): undefined | FeatureSymbology.Overrides Protected TileTreeReference Return overrides that replace any defined for the view.
getToolTipPromise(hit: HitDetail): undefined | Promise<undefined | string | HTMLElement> TileTreeReference Obtain a tooltip describing the specified hit, or undefined if this tile tree reference cannot supply a tooltip for the hit.
getViewFlagOverrides(tree: TileTree): Partial<Mutable<NonFunctionPropertiesOf<ViewFlags>>> Protected TileTreeReference Supply overrides that should be applied to the ViewState's ViewFlags when drawing this tile tree reference.
unionFitRange(union: Range3d): void TileTreeReference Unions this reference's range with the supplied range to help compute a volume in world space for fitting a viewport to its contents.
createFromRenderGraphic(args: RenderGraphicTileTreeArgs): TileTreeReference Static TileTreeReference Create a TileTreeReference that displays a pre-defined RenderGraphic.

Properties

Name Type Description
_layerIndex Protected number    
_layerSettings Protected MapLayerSettings    
_transparency Accessor ProtectedReadOnly undefined | number    
imageryProvider Accessor ReadOnly undefined | MapLayerImageryProvider Returns the imagery provider for the tile tree.  
iModel IModelConnection    
isOpaque Accessor ReadOnly boolean Returns true if the associated map layer, including its sublayers, is opaque.  
layerIndex Accessor ReadOnly number Returns the index of the map layer associated with the tile tree.  
layerName Accessor ReadOnly string    
layerSettings Accessor MapLayerSettings Returns the layer settings for the map layer.  
transparency Accessor ReadOnly undefined | number Returns the transparency value of the map layer.  

Inherited properties

Name Type Inherited from Description
_isLoadingComplete Accessor ProtectedReadOnly boolean TileTreeReference Override if additional asynchronous loading is required after the tile tree is successfully loaded, to indicate when that loading has completed.
castsShadows Accessor ReadOnly boolean TileTreeReference Return whether the geometry exposed by this tile tree reference should cast shadows on other geometry.
collectTileGeometry undefined | (collector: TileGeometryCollector) => void TileTreeReference  
isGlobal Accessor ReadOnly boolean TileTreeReference Return whether this reference has global coverage. Mapping data is global and some non-primary models such as the OSM building layer have global coverage
isLoadingComplete Accessor ReadOnly boolean TileTreeReference Return true if the tile tree is fully loaded and ready to draw.
The default implementation returns true if the tile tree loading process completed (whether it resulted in success or failure).
treeOwner Accessor AbstractReadOnly TileTreeOwner TileTreeReference The owner of the currently-referenced TileTree. Do not store a direct reference to it, because it may change or become disposed at any time.
